Rob Lowe, treating his sons to some dining, D.C. power-broker-style, on Wednesday -- first, at the White House mess, where they were seen lunching with an Obama staffer ("Welcome to the West Wing!" one fan of Lowe's old show stopped by to say, probably not the only one that day); and later at the Palm, with a couple other adults. Earlier in the week the star chaperoned a larger group of teens from his son's class doing the D.C. museum thing.
